Limited risk is a key benefit of options trading, particularly when buying calls or puts. The risk is limited to the premium paid for the option, which is the most you can lose. This makes options a capital-efficient way to gain exposure to an asset, as you don't need to commit a large amount of capital to buy the underlying asset outright.

Here are some key points about limited risk:

1. _Defined risk_: The risk is defined and limited to the premium paid for the option.

2. _No margin calls_: You won't receive margin calls or be required to deposit additional funds if the market moves against you.

3. _No unlimited losses_: Your potential losses are capped at the premium paid, unlike holding the underlying asset, where losses can be unlimited.

4. _Capital efficiency_: Options allow you to gain exposure to an asset with a smaller amount of capital, making them a capital-efficient way to trade.

5. _Risk management_: Limited risk makes it easier to manage risk and adjust your position as market conditions change.

Remember, while options trading involves limited risk, it's still important to thoroughly understand the terms and conditions before entering into any options transaction.
